COMPOUND FOR CLEANING MARBLE, STONE, 8w.

No Drawing.

To all whom it may concern.-

Be it known that I, RICHARD THOMAS CoNLoN, a citizen of the United States, residing at 903 Park avenue, in the city and county of New York, State of New York, have invented a certain new and useful Improvement in Compounds for Cleaning Marble, Stone, &c., of which the following is a specification.

My invention relates to cleansing and renovating compounds for the removal of stains of all kinds, grease, dirt, foreign material, etc., from marble and stone generally, statuary, wood work, and painted, varnished and enameled surfaces, floors, walls, windows, trim, looking glasses, oil- (loth, linoleum, metal and metal ware, crockery, etc. and for bleaching, renovating and polishing the same.

It consists of a compound, the composition of which is fully set forth hereinafter, said compound having the properties of cleansing dirt, stains and foreign material from the pores, removing grease and bleaching and renovating stone, marble and other surfaces. Heretofore marble. and stone generally to which this compound is particularly adapted as a. cleansing agent, was cleaned principally by the use of a chisel or other mechanical means removing considerable of the surface and often ('lefacing the same, strong acids or poisonous compounds which eat into the stone or other material destroying or damaging the surface, or rubbing with a piece of stone abrading the surface, but in all of these instances the work is slow, expensive and very destructive of the surface operated upon and such treatment is only adapted to stone and could not he -used for the various purposes set forth above.

The object of this invention is to produce a compound capable of cleaning, renovating and improving nearly all articles particularly marble and lime-stone and all manner of stones, said compound to be cheap and easy to manufacture and perfectly uninjurious in its nature.

The composition I prefer is as follows To 7 oz. of elastic starch add 5 oz. sodium carbonate all in finely pulverized condition mixed dry to form a powder. The powder so formed is to be mixed with an equal quantity of cold Water to form a paste. This paste is then to be mixed with boiling water Specification of Letters Patent.

Application filed March 11, 1919.

Patented Mar. 30, 1920.

Serial No. 282,015.

In the above compound the elastic starch is used to give the mixture body and evenness, and to prevent it from streaking. The sodium carbonate enters the pores and cleans the surface and removes the dirt and in the case of stone and marble, bleaches it and restores the original color and extracts and removes all grease and foreign material. The above substances are thoroughly mixed together dry or as a paste and in that condition the compound is to be packed in tins, boxes or other containers.

Although I prefer the proportions named above, I do not confine myself to those exact quantities as they may be varied without practically deviating from the invention The main features of this compound are that it has the properties of cleansing and removing grease, dirt and stains and bleaching combined and operates without streaking or staining and without injuring the surface in any way, and is non-poisonous and is economical, simple and easy to prepare and handle.

- I am aware that a composition consisting of marble dust, whiting, bicarbonate of soda, borax and sodium carbonate with or without cyanid of potassium has been used for the same purpose and Letters Patent therefor granted to Samuel C. (.avin, as assignee of Benjamin Greenfield, August 16th, 1881., being Number 245,713. I am also aware that sodium carbonate has been used in compounds for cleaning and renovating stone and marble, but I am not a ware that the ingredients of my compound have been .used together.

I now describe my invention and what I claim is new, and desire. to secure by Letters Patent.

A composition consisting of, ap n'oximately seven ounces of elastic starch, five ounces of sodium carbonate and a liquid for forming the same into a paste.

In testimony whereof I affix my signature this 6th day of March, 1919.

RICHARD THOMAS ONLON.
